GRAIN-DRILL GEAR.

SPECIFICATION forming part of Letters latent N 0. 643,447, dated February 13, 1900.

Application filed November 13,1899. Serial No. 786,722. (No model.)

To @U whom it may concern:

Be it known that we, DAVID J. AMEs and HENRY N. LABARE, of Owatonna, county of Steele, and State of Minnesota, have invent ed certain new and useful Improvements in Grain-Drill Gears, of which the following is a specification.

This invention relates to improvements in grain-drills; and the objects we have in view are to provide improvements in the gears by which the cup-wheels are operated and in the means for operating said gears, so as to throw them into or out of'connection with the driv ing-wheels.

Other objects of the invention will appear from the following detailed description of the invention, taken in connection with the accompanying drawings, in which Figure l is a longitudinal section through a portion of the grain-hopper, the hub of one of the. driving-wheels, the axle upon which said wheel is mounted, and other parts in connection therewith. Fig. 2 is a section on line w as of Fig. 1 looking in the direction of the arrow. Fig. 3 is a section on line 3 y of Fig. 1, also looking in the direction of the arrow. Fig. 4 is a section on line 2 z of Fig. 1 looking in the direction of the arrow. Fig. 5 is a section on line 12 o of Fig. 2 looking downward, as indicated by the arrow in said figure.

In the drawings, 2 represents a portion of the grain receptacle or hopper, which is provided with a cast plate 3, forming the end of the hopper, and formed integrally with said end 3 is the short hollow stub-axle 5, upon which is mounted a suitable supporting and driving wheel 7. The grain-drill is provided with the cup-casings 9, suitably located beneath the grain-hopper, and with the cupwheels 1.1, mounted upon the cup-rod 13. An internal ring-gear 15 is mounted upon the end of the cup-rod 13, so that when said gear, is rotated said rod and the cup-wheels mounted thereon are also rotated. A short shaft 17 passes through the hollow axle 5, its outer end being supported on the wheel-hub by means of the rectangular collar 19, (see Fig. 4,) which fits into a rectangular recess in the end of the wheel-hub, whereby said short shaft 17 is rotated at all times with the wheel 7. The opposite end of the shaft 17 passes through an adjustable box 21 and carries upon its end a pinion 23. This pinion is located within the internal gear 15. The adjustable box is connected to the pivoted 1ever 25, carrying at its end a weight 27. A shaft 29, provided with an arm 31, is adapted to engage a projection 33" on the weight 27, and thereby when the shaft 29 is rotated the weight 27 and the end of the lever 25 may be raised, thereby moving the adjustable box 21, the end of the shaft 17, and the pinion 23, carried upon said shaft. This movement of the lever 25 and box 21 brings the pinion 23 into substantially the position shown by full lines in Fig. 3, so that said pinion,with the shaft 17, may rotate with the wheel 7 without driving the gear 15. The shaft 29 being turned in the opposite direction, the weight 27 drops, moving the long end of the lever 25 downward, and thereby moving the box 21 inward and moving the pinion 23 from the position shown in full lines in said figure to the position indicated by dotted lines in the same figure, and thereby bringing the pinion 23 into mesh with the internal gear 15. When the pinion 23 is in mesh with the gear 15, said gear, the rod 13, and all of the cup-wheels 11 will be rotated with the shaft 17. When the pinion 23 is out of mesh with the gear 15, the shaft 17 and said pinion 23 will rotate idly without driving the gear 15. As shown in Fig. 2 of the drawings, the opening through the axle 5 is of oblong form in cross-section, so as to permit the shaft 17 to be moved freely in the opening in said axle. We may also provide an oil-duct 35, extending downward inside the end of the hopper for the purpose of permitting the gear 15 and pinion 23 to be lubricated. No claim is made herein to the particular arrangement or form of the cup-wheel or its casing or the means for supporting and turning said cup-wheel, as the same may obviously be varied in many particulars without departing from our invention.

The device, it will be seen, is exceedingly simple in construction and the hopper itself forms the axle and the frame of the drill. The construction is thereby very much simplified and the efficiency and ease of operation of the device are very largely increased.

\Ve have not shown herein the complete drill, believing this to be unnecessary. It will be understood, however, that the wheel 7 is of suitable construction to, in conjunction with a similar wheel at the other end of the machine, properly support the mechanism of the drill.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. The combination, with the hollow axle 5, of a suitable shaft arranged in said hollow axle and connected to the driving wheel, a pinion supported upon said shaft, a gear for moving the pinion carrying shaft so as to bring said pinion into or out of engagement with said gear-wheel, for the purpose set forth.

2. The combination, with the gear for driving the cup-wheel-operating rod, of the laterally-movable shaft 17 carrying a suitable pinion adapted to mesh with said gear, means connecting said shaft with the driving-wheel and means for laterally moving said shaft, for the purpose set forth.

3. The combination, with the hollow axle 5, of a laterally movable shaft 17 extending therethrough, means connecting the outer end of said shaft with the hub of the drivingwheel, a pinion 23 mounted upon the inner end of said shaft and adapted to engage a gearwheel upon the cup-wheel-operating rod, an adjustable box supporting the inner end of the shaft 17 and a lever connected to said box whereby the inner end of said shaft may be moved laterally to bring the pinion carried thereby into or out of engagement with said gear, for the purpose set forth.

4. The combination, in a grain-drill, with the grain hopper or receptacle 2 havinga castmetal end 3, a hollow stub-axle 5 formed integrally with said east end 3, a driving-wheel 7 mounted upon said axle, a shaft 17 arranged in said hollow axle and laterally movable therein, means connecting the outer end of said shaft to the hub of said wheel, a pinion carried by the inner end of said shaft, a gearwheel mounted upon the cup-wheel-operating rod, and means for laterally moving the inner end of the shaft that is arranged in said hollow axle, forthe purpose of moving its pinion into or out of mesh with said gear, for the purpose set forth.

In testimony whereof we have hereunto set our hands this 12th day of October, 1899.
